Definitions

  • the invention relates to a process for pressing bodies of artificial resins.
  • pressing artificial resin bodies and in particular such as are composed of fibrous material impregnated with phenol resins the pressing of which is carried out in the hot state, it has been found practically impossible to prevent the adhesion of the artificial resin bodies to the parts of the form or the dies of the press.
  • the invention has for its object to eliminate these drawbacks, and substantially consists in incorporating a form lubricating means in the surface of the body to be pressed which contacts the form. Tests made have shown that the die does not stick or adhere to the form if the process according to the invention is applied.
  • the incorporation of the lubricating means in the surface zone of the stamped body, contacting the form parts may be carried out in such a manner that at least one fibrous layer containing a lubricating means for the form is provided in the contacting zones.
  • the invention may be realized in a simple manner by adding the lubricating means required at least to one of the layers adjacent to the form.
  • the drawing shows an artificial resin body in side elevation by way of example, said body being composed of various fibrous layers which are impregnated with artificial resins.
  • the layers of the fibrous substance bodies containing artificial resins are designated by the numerals i and 2, Whereas the fibrous layers containing the lubricating means for the form are designated by the numerals 3 and. 4.
  • the fibrous substance bodies containing artificial resins and the fibrous layers containing the lubricating means may either be united in advance of the pressing operation and thus introduced into the press as a unit, or the individual layers may be inserted into the press separately, whereupon the press is closed, and the layers are heated.
